Chemical Structure
Description
4-(2,5-Dimethoxyphenyl)-1,1,1-trifluorobut-3-en-2-one (CAS 1007105-55-6) is a high-purity analytical reference standard with the molecular formula C12H11F3O3 and a molecular weight of 260.21 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 4-(2,5-Dimethoxyphenyl)-1,1,1-trifluorobut-3-en-2-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 260.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 4-(2,5-Dimethoxyphenyl)-1,1,1-trifluorobut-3-en-2-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
